I know what you mean -- after being a 2X for so long I still am surprised when I try on a 1X and it's roomy. I haven't quite gotten to the point of trying clothes from the "normal" section -- I guess I'm afraid of disappointment! Most of my pants are elastic waist so I have no idea what size I should be -- I just know some of the larger pairs now look like clown pants.

I did, however, purchase a band t-shirt at a concert in an L, looking to the future.

I guess I'm in reverse denial! Couldn't ever believe I'd gotten as large as I was, and now I can't believe I'm smaller!

I relate as well. I've been so used to buying clothes in baggy styles to hide my body that I'm not even sure what styles and materials might flatter my body now. My habit is still to wear blousey shirts and things rather than show my shape.
